Listen. The trees in this story are stirring, trembling, readjusting themselves. A breeze is coming in gusts off the sea, and it is almost as if the trees know, in their restlessness, in their head-tossing impatience, that something is about to happen.

I still have a stammer. I hate it; I loathe and despise it. But it's always there, and I have lots of ways to conceal it. I can conceal it now but I'm not good on the telephone. I get my husband to make dentist appointments. And I hate live radio. Hate it. I really try to avoid it at all costs. But it's always there. Stammerers become skilled at sentence construction and synonyms: we have to be. Faced with a problem word, we need to have instant access to eight others we could use instead - ones we could say without stumbling. I think my stammer is a huge part of my being a writer.

I don't want to be influenced as to what I write in the next book, to hear those voices in my head when I'm writing. The idea of second-guessing your reader is dangerous, trying to please some notional reader looking over your shoulder, instead of just yourself.

I have two sisters, and I think siblings are always going to be irresistible for novelists. They have been throughout time and they'll continue to be.

I always had the urge to write. Not in the sense of wanting to be a writer, but just writing things down, getting words on a page. Graphomania, it's called. I've always had a definite love of stationary products - I used to spend all my pocket-money on pens and notepads. I still do, in a way.

It is a terrible thing to want something you cannot have. It takes you over. I couldn't think straight because of it. There was no one else, I realized, whom I could possibly tell.

Something that had an enormous influence over my relationship with language was my stammer. I had a really bad stammer in my childhood and adolescence, and that imbues you with two things. First, a hyper-sensitivity to grammar, because a stammerer will have problematic sounds, impossible verbal stumbling blocks. Second, writing is just such a joy when you have a problem with speaking. It's so astonishing to watch language coming out of your pen without any hesitation or dysfluency.
